Choosing among FPV motors & ESCs gets tricky when four motors offer different model sizes, KV selections, and prices. The useful shortcut is to match the motor to the build cue you actually have-such as a named freestyle application or a specific KV-then use the price spread as a tie-breaker, rather than treating any number as a performance ranking.
Quick take
No single number settles this comparison. Start by identifying whether your build prioritizes the lowest listed price, a named freestyle use case, a particular KV selection, or a motor model and measurement. Then read the corresponding note below. The KV, shaft, cable, and size figures are matching references; the descriptions do not establish that a higher or lower number is automatically better.
Listed-price comparison
The four choices have a $14.00 spread between the lowest and highest listed prices. The bars show relative price position only; they are not a performance rating.
| Motor | Listed price | Price position |
|---|---|---|
| FS 2204 ELITE FPV Drone Motor | USD 21.50 | |
| BSC 2207.5 V2 FPV Drone Motor | USD 15.99 | |
| BSC 2812 FPV Drone Motor | USD 29.99 | |
| P1604 FPV Brushless Motor | USD 21.16 |
Decision matrix
- Price-first route: BSC 2207.5 V2 FPV Drone Motor occupies the lowest listed-price position in the comparison.
- Named application route: P1604 is explicitly described for a 3.5'' freestyle drone, giving it the clearest use-case cue.
- 1900KV route: FS 2204 ELITE FPV Drone Motor carries the 1900KV selection.
- 1155KV route: BSC 2812 FPV Drone Motor carries the 1155KV selection.
- Physical-reference route: The listed motor sizes are 24.3 × 17.25 mm, 27 × 32.3 mm, 33.6 × 41.7 mm, and 20.8 × 15.5 mm respectively. Compare those raw measurements with your own frame and hardware requirements, without treating size as a performance ranking.
Product notes
FS 2204 ELITE FPV Drone Motor
The red FS 2204 ELITE FPV Drone Motor gives a clear reference around its 1900KV attribute and 130 mm cable. Its description also lists a 1.5 mm shaft diameter and 24.3 × 17.25 mm motor size, useful measurements to compare with a planned build. Choose it when those specific cues matter more than selecting by price alone. The limitation is straightforward: at $21.50, it is not the lowest-priced motor in this group. Its title identifies the 2204 format, so a design calling for another model format should be evaluated against the other names here rather than assumed interchangeable.
BSC 2207.5 V2 FPV Drone Motor
The BSC 2207.5 V2 FPV Drone Motor is the lowest-price starting point at $15.99 and carries a 1950KV selection. Its description lists a 27 × 32.3 mm motor size, 4 mm shaft diameter, and 150 mm cable, giving a practical set of measurements for comparison with your build plan. Choose it when the 2207.5 model and 1950KV cue are the intended match. The limitation is that the title presents 1750KV, 1950KV, and 2100KV labels, while the compared attribute identifies 1950KV; treat the chosen configuration specifically rather than reading the title as one fixed KV.
BSC 2812 FPV Drone Motor
The BSC 2812 FPV Drone Motor is the choice to examine when 1155KV is the targeted selection. It lists a 250 mm cable and 5 mm shaft diameter, along with a 33.6 × 41.7 mm motor size; those raw values help you compare the part with the measurements your build requires. The $29.99 price gives it the highest listed cost in this group, which is its main limitation for a shopper using price as the deciding filter. Choose it for the model and KV cue, not simply because its numeric dimensions are larger or smaller than another motor: the information here does not establish a performance ranking.
T-Hobby P1604 KV2850 6S/ KV3800 4S FPV Brushless Motor For 3.5'' Freestyle Drone
The P1604 is the use-case-led choice: its title names a freestyle drone application, while the description identifies two cell pairings. That direct application language is a concrete reason to consider it when your build is described the same way. It is priced at $21.16 and lists a 2 mm shaft, 120 mm cable, and 11.6 g weight. The limitation is quantity: the packing list specifies 1 x P1604 brushless motor, so it is described as a single motor rather than a multi-piece motor-and-ESC set. Select the cell pairing that matches your planned configuration.
Final recommendation by use case
- Lowest listed price: Choose the BSC 2207.5 V2 FPV Drone Motor when its 2207.5 model and 1950KV selection match your build.
- Freestyle drone application: Choose the P1604 when the freestyle use case named in its title and one of its stated cell pairings align with your setup.
- 1900KV requirement: Choose the FS 2204 ELITE FPV Drone Motor for the 1900KV selection, red color, and 2204 model cue.
- 1155KV requirement: Choose the BSC 2812 FPV Drone Motor for its 1155KV selection, while accepting its position at the top of the listed price range.
The practical winner depends on the cue your build already establishes. Match KV and cell pairing first, then use model details and price to narrow the choice.
